<h2>Detailed Description</h2>
<p>The QAccessibleBridge class is the base class for accessibility back-ends.</p>
<p>Qt supports Microsoft Active Accessibility (MSAA), Mac OS X Accessibility, and the Unix/X11 AT-SPI standard. By subclassing QAccessibleBridge, you can support other backends than the predefined ones.</p>
<p>Currently, custom bridges are only supported on Unix. We might add support for them on other platforms as well if there is enough demand.</p>
<p>See also <a href="qaccessible.html">QAccessible</a> and <a href="qaccessiblebridgeplugin.html">QAccessibleBridgePlugin</a>.</p>

<h2>Member Function Documentation</h2>
<h3 class="fn"><a name="dtor.QAccessibleBridge"></a>QAccessibleBridge::~QAccessibleBridge ()&nbsp;&nbsp;<tt> [virtual]</tt></h3>
<p>Destroys the accessibility bridge object.</p>
<h3 class="fn"><a name="notifyAccessibilityUpdate"></a>void QAccessibleBridge::notifyAccessibilityUpdate ( int <i>reason</i>, <a href="qaccessibleinterface.html">QAccessibleInterface</a> * <i>interface</i>, int <i>child</i> )&nbsp;&nbsp;<tt> [pure virtual]</tt></h3>
<p>This function is called by Qt to notify the bridge about a change in the accessibility information for object wrapped by the given <i>interface</i>.</p>
<p><i>reason</i> specifies the cause of the change. It can take values of type <a href="qaccessible.html#Event-enum">QAccessible::Event</a>.</p>
<p><i>child</i> is the (1-based) index of the child element that has changed. When <i>child</i> is 0, the object itself has changed.</p>
<p>See also <a href="qaccessible.html#updateAccessibility">QAccessible::updateAccessibility</a>().</p>
<h3 class="fn"><a name="setRootObject"></a>void QAccessibleBridge::setRootObject ( <a href="qaccessibleinterface.html">QAccessibleInterface</a> * <i>object</i> )&nbsp;&nbsp;<tt> [pure virtual]</tt></h3>
<p>This function is called by Qt at application startup to set the root accessible object of the application to <i>object</i>. All other accessible objects in the application can be reached by the client using object navigation.</p>
